Unroll cake; spread thinly with some of the Mocha Butter Cream; then with whipped cream; roll up.

Frost with remaining Mocha Butter Cream (see recipe); mark with spatula to resemble bark. Cut off a thin slice; reroll to resemble stumps of cut-off branches; place on top. Decorate with vine and leaves made with green icing; sprinkle here and there with flaked coconut to resemble snow and chopped pistachio nuts to resemble moss. Chill or freeze until ready to serve. Makes 12 servings.
